FloodSax (pack of 5 or box of 20)
Very good company to work with, they were let down by UPS, they only delivered 3 of the 4 parcels but quickly sent another two.
2 did not work at all, then another 2 split when used as flood barrier went flat and let the water over the top
Bought these to prepare for an emergency, so haven’t used yet but they do look very good & real quality. Will wait & see when they’re needed.
Just the job
